Stormwater Management Stormwater will be managed on -site and will conform with applicable Rice Creek Watershed District requirements. Due to limitations regarding infiltration viability of existing subsoils (HSG type D soils) the stormwater management system will consist of three (3) stormwater/NURP ponds along the west and northwest portions of the site Wetland Impacts A wetland delineation and report was completed by Kjolhaug Environmental Services in 2018. There is a small de minims wetland 0.03 acres in the middle of the site that will be impacted with the construction of the project. We will apply for wetland permitting with Rice Creek Watershed District. De min imis wetland impacts do not require WCA mitigation. Landscaping The proposed landscape design is a diverse selection of trees, shrubs, grasses, and ground covers which will provide an esthetically pleasing experience while also fulfilling the requirements of the City zoning code. Landscaping zoning requirements: The quantity of proposed trees and shrubs has been determined by the landscape standards in the city code. Tree calculations are based on 1 tree / 3000 SF of the disturbed site area (29.79 AC/1,297,774 SF). The total quantity of trees required is 433. The total quantity of shrubs required is based on 1 shrub / 10 LF of the building perimeter of 1,702.83 LF and the perimeter of the parking lot that is 4,979 LF. The total quantity of shrubs required is 668. Outside of the proposed building and hardscape elements, the entire portion of the disturbed site will be landscaped and irrigated. This will be accomplished by using a combination of trees, shrubs, ornamental grasses, native prairie plants, and turf. The diverse selection of trees & shrubs consists of thirteen (13) species of deciduous trees, five (5) species of evergreen trees, six (6) species of deciduous shrubs, four (4) species of evergreen shrubs and five (5) species of grasses. With a broad mixture of species, the planting pallet will provide a wide variation of height, shape, texture, and canopy coverage. In order to provide loading area screening above and beyond that of the vegetation, there will be a 6' tall opaque fence adjacent to the parking areas along the South side of the site and portions of the West & East property lines. See the attached 3D images for the site line views from the roads. As the planting plan illustrates, there is a significant quantity of trees on the north side of the building which may not be of the highest benefit to the public. If some of these trees would provide a higher aesthetic value to a public venue the development would entertain placement of the required trees in a public venue instead of on site. Monument Signage There are two monument signs proposed, one at the northern access to 21 st Avenue and one at the middle access to 21 st Avenue. Anticipated Schedule • Construction Start: July 2022 • Occupancy: August 2023
